Figure 4

The Figure 4 is a DLP 3D printer from 3D Systems with a 125 x 70 x 196 mm build volume.

Specifications

The 3D Systems Figure 4 is a projector-based stereolithography (SLA/DLP) resin 3D printer, not a Fused Deposition Modeling (FDM) printer [1, 2]. Because of this, several traditional FDM specifications (like hotends and nozzles) do not apply to this machine.

Here is the verification of the technical specifications based on the provided sources:

• Hotend & Nozzles: Not applicable. Instead of a hotend and nozzle, the Figure 4 uses a digital-projection light source (a high-powered 405 nm UV projector) to cure liquid photopolymer resins .

Calibration

The 3D Systems Figure 4 is an industrial projector-based resin 3D printer (Vat Photopolymerization), rather than an FDM (Fused Deposition Modeling) printer [1, 2]. Because it uses a UV projector to cure liquid photopolymer resin an entire layer at a time, FDM-specific calibrations such as e-steps, flow rate, PID tuning, retraction, and pressure advance do not apply to this machine..
